is cross building NetBSD-alpha on an i386 system supposed to work?
   Building a kernel dies for me like this:
   
   /src/tools/bin/alpha--netbsd-gcc  -mno-fp-regs -ffreestanding  -O2 -Werror -Wall -Wno-main -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes -Wno-uninitialized  -Dalpha -I.  -I/usr/src/sys/arch -I/us
r/src/sys -nostdinc -DDIAGNOSTIC -DLKM -DMAXUSERS=32 -D_KERNEL -D_KERNEL_OPT   -c /usr/src/sys/dev/ic/am7990.c
   /usr/src/sys/dev/ic/am7990.c: In function `am7990_meminit':
   /usr/src/sys/dev/ic/am7990.c:192: Internal compiler error in `alpha_expand_unaligned_load', at config/alpha/alpha.c:1617

as reported multiple times over the past few weeks, this is known to
be broken.  "don't do that."
